中文阅读中长距离回视引导机制的眼动研究

从记忆的角度, 探讨中文阅读中长距离回视的引导机制。采用眼动实验, 操纵了回视条件(实验1)、回视可见性(实验2)、目标词位置及词频变量。结果发现:与不阅读组相比, 阅读组的最初回视误差更小, 定位效率更高; 与可见组相比, 不可见组累积回视距离更大, 且难以正确定位目标; 目标词位置主效应显著, 而词频主效应不显著。结果表明, 回视具有空间选择性, 最初的回视由空间记忆引导, 最初回视后的修正眼跳在文本可见情况下才能正常进行, 而词频这一言语属性对回视没有显著影响, 本研究结果支持了空间编码假设。

An eye movement study for the guidance mechanism of long-distance regressions in Chinese reading

Regression is one of a usual phenomenon in normal reading. But the eye movements go against normal reading order during regressions. According to the eye moving distance during regressing, researchers divide regressions into long-distance regressions and short-distance regressions. Some English studies suggest that long-distance regressions are guided by memory and two theories can explain the mechanisms of regression, which are the spatial coding hypothesis and the verbal reconstruction hypothesis. Both theories have their rationality and get some studies' supporting, but there are some arguments between them. The spatial coding hypothesis suggests that the eye movements are guided by spatial memory during regressions, but the other suggests that they are guided by verbal memory. And researchers find that first regression was always followed by some small corrective saccades. There is also no consensus among researchers on the guiding mechanism of corrective saccades. The purpose of this study is to explore the guiding mechanism of long-distance regression in Chinese reading and to provide new evidence for the resolution of this dispute.
